INFINEON IR21531DPBF Datasheet & Stock

The IR21531DPBF is a self-oscillating Half-bridge Gate Driver IC incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. The IC provides more functionality and is easier to use. A shutdown feature has been designed into the CT pin, so that both gate driver outputs can be disabled using a low voltage control signal. In addition the gate driver output pulse widths are the same once the rising under-voltage lockout threshold on VCC has been improved significantly, both by lowering the peak DI/DT of the gate driver and by increasing the under-voltage lockout hysteresis to 1V.
